Almost all of the drivers required to install Windows 7 on Z370 PC are available! (Only Coffee Lake IGPU does not have a Windows 7 compatible driver...)
You will need a dedicated graphics card because Windows 7 compatible driver for Coffee Lake IGPU is not available.
Windows 10 chipset and AHCI (SATA) drivers have native compatibility
with Windows 7 and Z370. No need to modify any driver!
Follow these steps:
On a Windows 7, 8, 8.1 or 10 working PC:
. Open Asus Maximus X Hero page: https://www.asus.com/ROG-Republic-Of...AXIMUS-X-HERO/
.Click on "Support".
. Click on "Driver & Utility". This page will open: https://www.asus.com/Motherboards/RO...Desk_Download/
. Select OS "Windows 7 64bit" and download: Audio driver, LAN driver and "ASUS_EZInstaller_1.03.16". You will not find here any chipset and SATA drivers!
Extract the zip files on a portable drive.
. Select OS "Windows 10 64bit" and download: Intel Chipset Driver (version 10.1.1.44 - 2017/08/30) and SATA drivers (version 220.127.116.117 - 2017/09/27). Extract the zip files on a portable drive.
. Get a Windows 7 x64 SP1 kit (DVD, or Windows 7 bootable USB drive). I have already had a Windows 7 Professional x64 SP1 bootable USB drive which i used to install Windows 7 on my ex Haswell-Z87 configuration. I made this bootable USB drive using a very nice and well known application: Rufus!
. Add usb 3.0 and NVMe drivers to windows 7 install.
Launch "ASUS_EZInstaller_1.03.16_20171031" (right click on "EZ Installer.exe", "Run as admin."). "Please select..." the option that suits you best and follow the rest of the steps.
I selected: "Update the original Windows 7 OS in the USB storage device". I inserted my Windows 7 bootable USB drive and i checked "NVMe" box (just in case someday i will use a SSD NVMe drive for OS). At the end, the USB 3.0 and NVMe drivers were slipstreamed into Windows 7 on my USB drive.
On your Coffee Lake PC:
. Install Windows 7.
Insert your Windows 7 bootable media, turn on or reboot the PC and press F8 (for Asus motherboards) at the beginning of the boot sequence in order to select the booting device.
Install Windows 7. (See picture 01) 01Systeminfo.jpg 159k .jpg file
. Install chipset driver.
After Windows 7 installation, open the folder which contains files extracted from "Intel_Chipset_Win10_V101144_20170830_7.45.zip ".
"Run as admin" "SetupChipset.exe". It will work and the Z370 chipset driver will be installed.
Although on Asus site it is listed as Windows 10 driver, Intel Chipset Driver (version 10.1.1.44 - 2017/08/30) is Windows 7 & 8 compatible, as you will see if you read the "Readme File Information" which will be displayed at the beginning of the installation process (See picture 02). 02_IntelChipsetDeviceSoftware.jpg 251k .jpg file
Open "Control Panel/System & Security/System/Device Manager/System devices" if you want to check that the chipset (Z370) driver was installed. (See picture 03) 03_Systemdevices.jpg 133k .jpg file
I chose not to install "Intel Management Engine Interface"! It can be downloaded from Asus Maximus X Hero support page (2 versions available), but i don't know if it can be installed...
. Manually Install AHCI (SATA) driver.
Open "Control Panel/System & Security/System/Device Manager". Expand "IDE ATA/ATAPI controllers". Right click on "Standard AHCI 1.0 Serial ATA Controller" and select "Update Driver Software".
Select "Browse my computer for driver software" and browse for location where you extracted "RST_18.104.22.1687_20170913_WHQL.zip". Check "Include subfolders" box. (You can also try "Let me pick from a list of device drivers on my computer/Have disk" method).
If you open with Notepad the "iaAHCIC.inf" file, you will see that "PCI\VEN_8086&DEV_A282&CC_0106" (Intel 300 Series Chipset Family SATA AHCI Controller) is listed under Win7, despite the fact this driver is uploaded by Asus for Windows 10 only.
I chose not to install "Intel Rapid Storage Technology" software! I think it is possible to install it ("Run as admin." "SetupRST.exe") only after you manually install AHCI driver.
. Install network adapter, sound controller and dedicated graphics card Windows 7 compatible drivers. Done!
My "Device Manager" looks like picture 04. 04_DeviceManager.jpg 212k .jpg file
